Definitions
- the invention relates to a spinning station and an air-jet spinning machine for producing a yarn from a fed fiber sliver, with an air spinning nozzle with an inlet opening for the fed fiber sliver and an outlet area with an outlet opening for the spun yarn.
- the invention also relates to a method for producing a yarn with a modified surface structure.
- the invention relates to the use of a draw-off nozzle in the outlet region of the air-jet spinning nozzle of a spinning station for modifying the surface properties of an air-jet spun yarn.
- Spinning units and air-jet spinning machines are known in a variety of configurations from the prior art and represent, in addition to rotor spinning machines, frequently used machines for producing a yarn from a fiber material, in particular from a sliver fed to the spinning unit.
- a sliver or fiber sliver is typically drawn according to the yarn fineness to be achieved by means of a drafting system comprising several pairs of rollers and fed to the air-jet nozzle.
- a part of the supplied fibers is wound around the parallel fiber core by means of a rotating flow. This creates the air yarn-specific yarn structure of a parallel yarn core with wrapping fibers lying at a certain angle, which ensure the strength of the yarn. Since there are no mechanical points of contact when the fibers are twisted, air-jet yarn usually has particularly low hairiness.
- the proportion of protruding fibers can generally be influenced by changing the compressed air supplied to set the spinning pressure and / or changing the spinning speed. If the spinning pressure and / or the spinning speed change, however, other properties of the air-jet yarn are also negatively influenced, so that better hairiness can be achieved, but only with yarn properties such as yarn stability that are generally worsened at the same time.
- the invention is therefore based on the object of providing a spinning station, an air-jet spinning machine and a method which allow an advantageous modification of the yarn surface properties without at the same time deteriorating the yarn properties and thereby avoid expensive and complex modifications of the spinning station.
- the spinning station according to the invention for producing a yarn from a fed sliver has an air spinning nozzle with an inlet opening for the fed sliver and an outlet area for the spun yarn which emerges from an outlet opening in the outlet area. Also arranged downstream in the outlet area of the outlet opening in the direction of the yarn take-off is, according to the invention, a take-off nozzle for modifying the surface properties of the spun yarn.
- An air-jet spinning machine has at least one, preferably several and particularly preferably several identical spinning positions each for producing a yarn from a supplied sliver, the at least one spinning position and preferably all spinning positions being formed according to the invention.
- a yarn is first air-spun from a sliver by means of an air-jet nozzle and then the air-jet yarn is guided through a take-off nozzle to modify the yarn surface, which is preferably carried out as part of the removal of the yarn from the air-spinning nozzle he follows.
- the invention includes the use of a take-off nozzle in the outlet area of an air spinning nozzle of an outlet opening in the direction of a yarn take-off for modifying the surface quality of an air-jet yarn in a spinning station in particular according to the invention or in an air-jet spinning machine in particular according to the invention.
- the inventors have recognized that a direct influence on the air-jet spinning process, for example by changing the spinning parameters such as the spinneret geometry, the spinning pressure or the spinning speed, is not possible without associated disadvantages with regard to the yarn quality. Proceeding from this, it is part of the present invention that a surface modification of the air-jet yarn is carried out immediately following the air-jet spinning process, as a result of which the quality of the air-jet spun yarn due to the spinning process is not negatively influenced.
- the invention therefore enables the surface of a spun yarn to be modified without interfering with the spinning process, so that the spinning process is initially operated with the parameters that are optimal for it, in particular without taking into account aspects of the yarn surface properties, and then a change in the yarn surface properties using the take-off nozzle to a desired state can be made.
- This enables a significant expansion of the fields of application and the possible uses of air-jet yarn, in particular as a knitting yarn with an advantageous, softer and / or more fibrous or hairier surface.
